What do you want to know?
The recommended, safest, and simplest way to use Tor is to download the latest stable Tor Browser from https://torproject.org. You just unpack it wherever you want and run it. There's no installation. Voila, you're using Tor.
You can just browse the open web as normal, or visit hidden services with ".onion" addresses (the so-called "dark web" [eye-roll])
You can use other browsers and programs through a Tor proxy, but it's not as safe.
If you want to know more about it, go straight to the source. The guy who wrote Tor uses the nick "arma" on the Tor IRC channel, and he's often around and happy to answer questions. Great guy.
Using Tor is incredibly simple for noobs. Even setting up a hidden (.onion) service is easy if you just follow a few simple instructions.
As the other guy said, you will want to understand what kinds of protections Tor can and can not provide. Then you understand how to use it effectively to your best advantage. It's not rocket science.

Note that you may see a lot of bullshit around about how Tor is "compromised" or "backdoored" by the NSA, etc. etc. That's often just law enforcement or intelligence community shills trying to get people not to use it (because it works), or the morons they've bullshitted into believing them.
